Description
独立請求項1の特徴を有する半導体モジュールは、2つの半導体チップの間の電流ブリッジが、ハウジングの外部において閉成されているという利点を有する。これにより、導電素子のコンタクト始端における電流狭窄部と、それに伴う信頼性リスクとが、高電流密度と温度上昇とによって好適に排除され得る。本発明に係る半導体モジュールの実施形態は、ハーフブリッジ回路として好適に実施することができ、電気機械と共に直接「パワーパック」に組み立てられる電子回路支持体上の構造のために設けることができる。好適には、対応するハーフブリッジ回路の相電位タップは、半導体モジュールが配置されている回路支持体に相電流を流すことなく、電気機械のステータ巻線の相電流ワイヤに直接接続することができる。さらに、本発明に係る半導体モジュールの実施形態は、低いインダクタンスを有する電気的なブリッジパスを提供することができ、そのため、ハーフブリッジ回路は、好適には、高いPWM周波数(PWM:パルス幅変調)と小型化された受動構成素子とを有するパルスインバータ回路に使用することができる。
図1乃至図8から明らかなように、本発明に係る半導体モジュール1の図示の実施例は、それぞれ少なくとも2つの半導体部品10,20を備え、これらの半導体部品10,20は、それぞれハウジング3の内部で2つの導電素子12,14,22,24の間に配置され、当該導電素子12,14,22,24と導電的に接続されている。ここでは、これらの導電素子12,14,22,24は、それぞれハウジング3から引き出されたコンタクト突起12.1,14.1,22.1,24.1を有する。さらに、異なる平面内に配置された2つのコンタクト突起12.1,24.1は、ハウジング3の外部でコンタクト要素5を介して相互に接続されており、当該コンタクト要素5は、ハウジング3の外部で2つのコンタクト突起12.1,24.1の間に電流パスを形成する。
